That 305whp sentra, that 1439/2000 is talking about is mine.

And like you said, the poor turbo on the rb20 is the way nissan built the motor, if it was meant to be a motor nissan wanted to perfom why not go with a better turbo like SRs came with...I just think it is funny that a common upgrade for a rb20 is a z31 turbo which is just as old as an rb20.

As for you saying you have a friend pulling their rb25 to put in an rb20, makes sense, might as well put a motor in their car that will rev to something decent.

The rb20 motor is extremely outdated, honestly how many motors these days are cast iron? Not to mention you can find rb20s that are what almost 25 years old?
